'I have no idea, for the first time in a long time – actually at times it was the same under Louis Van Gaal - how they're going to play, who they're going to play, where they going to play.

'I couldn't tell you who's going to play in the next game for Manchester United if everyone is fit. They look as if they are all over the place.'

Scholes echoed McManaman's comments and believes his former club should look to utilise the experience of Michael Carrick if they are to halt their recent run of poor form.

'As much as you talk about formations and who should play where, the quality on the ball was as poor as you would see from a Manchester United team. That's just the way it is at the minute,' Scholes said.

'You're not sure what you're going to get. Rashford is the only shining light really. He didn't have the best game but he looked a threat. I just think in possession Manchester United were really, really poor.

'Individually it wasn't good enough. The possession wasn't good enough, they were sloppy giving the ball away.

'I thought [Marouane] Fellaini was alright today – he does a job in there which stops the team. I just think, if you're Manchester United, you need someone who can stop the opposition but he needs to be capable of controlling a game of football as well.

'Playing forward, passing forward. As well as he's done the first three or four games, I just can't understand why Michael Carrick [is not] there.

'It looked last year like he was leaving, he's not played a minute this season. What he's done I don't know. Obviously [Bastian] Schweinsteiger he's not keen on but they need that playmaker in there.'

Manchester United have now lost their last three games in all competitions

McManaman says Mourinho is already facing pressure after just seven games as United boss

McManaman also believes Mourinho is already facing pressure after just seven games as Manchester United manager.

'He can't lose again and again and again. You have to hit the ground running when you're at a big club,' McManaman said.

'We mentioned at the start of the season [there's] Klopp, Jose, [Conte] and Guardiola – only one of them is going to win the league.

'There's going to be pressure on the other three. The pressure is going to start straight away because the performances are not good enough.'
